The patch for #93131 increased the db size of field ses_id
in tables fe_sessions and be_sessions from 32 to 255 chars.
The field is the tables primary key.
With mysql/mariadb, if the table is created on an older db
engine version that creates innodb tables with COMPACT
row format using utf8_mb4 charset, the key length now
exceeds the COMPACT maximum index length restrition of 767
bytes: 4*255+1 = 1021 bytes
Since we don't strictly need a varchar(255), the patch
reduces the field to 190, which does not collide with
maximum key length restrictions: 4*190+1 = 761 bytes
